Effectivity of Anti-Spam
For the moment we're preparing to move our E-mailsystem to O365, using the online version of exchange. Actual we have another mailing system in use. The smtp requests from outside where scanned by the firebox and than forwarded to antispam-filter.
Is it a good idea to use the anti-spam functionality of the firebox instead of a specialized antispamsoftware?
Thanks in advance for your answers.
